How to run push notifications on MicroG in 2020?

Question

Android

Guys, good day! I have been looking for any information on this topic for a long time on different sites - there is no effect, I turn here.
As you know, since 2019, Google Cloud Message stopped working, FCM was launched instead. Installed on custom CarbonROM, MicroG. Push notifications do not come. GCM in the MicroG settings returns the information that they say Disconnected. GCM application list is empty. Notifications from applications do not come. All MicroG permissions granted, signature forgery active. Who faced, tell me what can be done.

Redmi 7 3\32
CarbonRomOS 8.0\Android 10
Magisk 20.4

Answer 1

You are doing something wrong while Google Cloud Message is still running.
For my tests, Redmi Note 3 Pro with Havoc OS on Android 9m, without dancing with a tambourine from the MicroG repository for F-Droid, I installed all the software after the firmware, Google cloud writes: Current State: Connected, just went in specially checked.
